Case Study: rKube accelerates Java modernization and boosts test coverage with IBM watsonx Code Assistant

Accelerating the Java software development lifecycle with IBM watsonx Code Assistant

rKube, a Morocco-based IT solutions provider specializing in modernizing IBM WebSphere applications and Java upgrades across EMEA, was struggling with the growing complexity of Java application modernization. Challenges such as poor documentation, large codebases, outdated testing, and heavy manual effort were slowing delivery and increasing costs.

rKube worked with IBM and IBM Client Engineering on a six-week proof of concept using IBM watsonx Code Assistant. The solution automated code transformation, generated unit tests, and provided explanatory analysis, helping rKube transform 80% of in-scope WebSphere code automatically and raise Java unit test coverage to 90%, while improving efficiency and quality.
